43 operations being pulled away from.Pull-off with circle shape part 45 relative to the cylindrical body 43, the limitation based on circle shape part 45
The locking relationship of the claw 39 of claw 48 and latch for printed circuit 37, collet 30 are pulled out from sleeve 29.If the set for being drawn out this
Pawl 30 is radial to be reduced, by the locking relation broken of the limitation claw 48 of circle shape part 45 and the claw 39 of latch for printed circuit 37, then
Collet 30 is detached from from circle shape part 45.Then, by the multiple latch for printed circuit 37 for the long size collet 30A that should newly install to annulus
The medium pore 45a of shape component 45 is pushed into, and the claw 39 of latch for printed circuit 37 is made to be locked on the limitation claw 48 of circle shape part 45,
Under this state, it will be inserted into one end lateral sleeves 29 of the long size collet 30A.Then, if circle shape part 45 used
Clamp 46 is installed to cylindrical body 43, then long size collet 30A is set in sleeve 29 (state shown in Fig. 6, Figure 12).
In the above-described embodiment, the stage portion 43a based on the medium pore Inner peripheral portions of pulley 51 towards cylindrical body 43
Structure, by the way that only circle shape part 45 is removed, to collet 30 (30A) be pulled out from sleeve 29, but as variation,
Stage portion 43a can not be formed in cylindrical body 43, by cylinder-like part (cartridge and not removing clamp 46
(circle shape part 45 and cylindrical body 43)) 42 itself pull-out, so that collet 30 (30A) be pulled out from sleeve 29.In addition, can also
In the state of not form stage portion 43a in the cylindrical body 43, by the way that circle shape part 45 is torn open from cylindrical body 43
Under, so that collet 30 (30A) be pulled out from sleeve 29.
In addition, drill bushing 5 is installed at deep hole processing machine 2 (apparatus main body) when carrying out deep hole machining to the long dimension workpiece,
At pressing device 10, it will push against stick 72 instead of push rod cup 73 and be installed to telescopic rod 71 (referring to Fig.1 2).
After replacing the 2nd endless member 57 and long size collet 30A, deep hole machining is being carried out most to long dimension workpiece WL
Just, as shown in figure 12, the state left for above-mentioned chuck device main body 9 relative to deep hole processing machine 2, in this state, long ruler
Very little workpiece WL is defeated by upper direction chuck device main body 9 of the conveying device 84 between deep hole processing machine 2 and chuck device main body 9
It send.In the case, as conveying device 84, the axle portion W1 of long dimension workpiece WL is pressed from both sides with a pair of of holding tool 85 using having
The structure for the clamping device 86 held, the conveying device 84 can along the vertical direction and transverse shifting.Based on this, conveying device 84 exists
When the conveying of long dimension workpiece WL, the axle portion W1 of long dimension workpiece WL is clamped by clamping device 82, is become the long size
The axle portion W1 of workpiece WL remains level and the state by its umbrella portion W2 towards 5 side of drill bushing, makes the long dimension workpiece with the state
WL decline.Then, if the umbrella portion W2 of long dimension workpiece WL reaches the height and position of drill bushing 5, conveying device 84 pass through to
It is mobile close to the direction of drill bushing 5, the umbrella portion end face W2 of long dimension workpiece WL is pushed to drill bushing 5 to (the referring to Fig.1 2, arrow in Figure 13
Head).
If the umbrella portion end face W2 of long dimension workpiece WL is pushed into drill bushing 5, glide base 6 is driven, and is based on this, such as
Shown in the arrow of Figure 13, the axle portion W1 of long dimension workpiece WL starts by relatively to the 2nd endless member 57 of chuck device main body 9
Through hole 64 in insertion.
If passing through the driving of glide base 6, the axle portion W1 of long dimension workpiece WL is relative to the phase in chuck device main body 9
Pair entrance continue to progress, then the 2nd endless member 57 is connected to by the umbrella portion back side W2 for the long dimension workpiece WL that drill bushing 5 supports
The movement of recess inner surface 63a, glide base 6 (chuck device main body 9) are limited.Long dimension workpiece WL phase has been carried out as a result,
Positioning for long size collet 30A.At this point, the axis direction length of the axle portion W1 of long dimension workpiece WL is than long size collet
The length of chuck device main body 9 on the axis direction of 30A is long, but in the axle portion W1 for making long dimension workpiece WL to long size collet
When 30A is inserted into, since chuck device main body 9 is the construction that the axle portion W1 of long dimension workpiece WL can be made to penetrate through, so can incite somebody to action
Long dimension workpiece WL is reliably retained in long size collet 30A.
If having carried out positioning of the long dimension workpiece WL relative to long size collet 30A, will be pushed away by cylinder driving device 75
Pressure device 10 (moving body 67) is mobile towards chuck device main body 9 on glide base 6, the cylinder 69 of the pressing device 10
The annular end face of (other side part 69b) is as shown in figure 14, and circle shape part 45 is pushed.Long size collet 30A direction as a result,
The one end of sleeve 29 relatively moves, and the internal diameter of long size collet 30A radially reduces, and the axle portion W1 of long dimension workpiece WL is by the length
Size collet 30A clamping.At this point, push rod 72 is in the state being pulled into cylinder 69, the axle portion of long dimension workpiece WL
The end face W1 does not push (referring to Fig.1 4) by the push rod 72.
If the axle portion W1 of long dimension workpiece WL is clamped by long size collet 30A, rifle drill 2A in drill bushing 5 by moving
To the umbrella portion end face W2 of long dimension workpiece WL, for long dimension workpiece WL, deep hole machining is carried out (referring to figure from its umbrella portion end face W2
14).At this point, since long size collet 30A is by the axle portion W1 clamping of long dimension workpiece WL, so with above-mentioned collet 30 is used
Situation compares the vibration for being able to suppress axle portion W1, can carry out the higher deep hole machining of precision to long dimension workpiece WL.
If terminated for the deep hole machining of long dimension workpiece WL, as shown in figure 15, rifle drill 2A is from chuck device master
It is exited in body 9, and the shortening campaign based on the telescopic rod of cylinder driving device 75 78, pressing device 10 is from chuck device main body 9
Slightly away from the pushing force that cylinder 69 applies circle shape part 45 is released from.Long size collet 30A is by long ruler as a result,

End face carries out deep hole machining.
In the case, due to using long size collet 30A as collet 30, so can be by long dimension workpiece WL's
Axle portion W1 throughout longer range clamp, can with higher reliability inhibit deep hole machining when axle portion W1 vibration.
On the other hand, about the workpiece WS of short size, if by its shorter axle portion W1 from relative to deep hole processing machine 2
(rifle drill 2A) is open compared with the another side of the sleeve 29 in distal side and is inserted into collet 30, even if the then axis of the short dimension workpiece WS
Portion W1 is shorter, can also utilize allocation position (the closer position of another side opening away from sleeve 29 of the collet 30 in sleeve 29
Set), by the relative movement of the collet 30 and sleeve 29 by the shorter axle portion W1 clip of the short dimension workpiece WS to the set
In pawl 30.At this point, rifle can be made to the external opening of chuck device main body 9 using each both ends open of collet 30 and sleeve 29
Pipe bores 2A and enters in sleeve 29 from one end side opening of sleeve 29, so even if not making chuck device main body 9 (collet 30 and sleeve
29) direction reversion also can carry out deep hole machining to the end face of the axle portion W1 of short dimension workpiece WS.
In particular, in the present embodiment, since the other end of sleeve 29 is the shell 12 from chuck device main body 9
The other end of width direction state outstanding slightly outward, so even if the axle portion W1 of short dimension workpiece WS is extremely short,
The shorter axle portion W1 can be open from the another side of sleeve 29 and be inserted into, reliably clip is into collet 30, in this way
The axle portion W1 of short dimension workpiece WS be also able to carry out deep hole machining.
